OS 11 Interdeck Car Park - Liquid Applied Surface Protection

The Wecryl Surface Protection System OS 11b (OS F) is a flexible PMMA waterproofing system that is approved in accordance with the DAfStb guideline on the "Protection and repair of concrete components” and in accordance with ZTV-ING – part 3 – section 4 "Protection and repair of concrete components". That makes this surfacing system suitable as a surface protection layer with improved dynamic crack bridging properties for areas subject to pedestrian and vehicular traffic.

The surface design can feature a wide range of colours as well as patterns or markings. The fact that this system, with its high bonding strength on almost any substrate, is applied as a liquid kit makes it a cost-efficient and high-quality solution, especially for the refurbishment of multi-storey car parks.

System components:

• Wecryl 171 - Low-viscosity primer for mineral substrates.
• Wecryl R 230 thix - Waterproofing resin.
• Wecryl 271 - Self-levelling, dynamic-crack bridging surfacing.
• Wecryl 419 - Textured surfacing.
• Wecryl 488 - Pigmented sealer (finish).
